FLEX-O-LATORS INC Product Lines We Repair
Our engineers are trained on the full FLEX-O-LATORS INC product range. Below are the major product families we service.
NG6 Series Proportional Directional Control Valves
Four/three-position proportional spool valves with integrated LS logic and onboard pilot stage amplifiers. Common faults include solenoid hysteresis, spool stiction from contaminated hydraulic fluid, and loss of null pressure due to pilot pressure leakage. Synchronics bench tests solenoid resistance, command signal verification, and hydraulic interface integrity.
Pilot-Operated Flow Control Regulators
Precision load-sensing proportional flow valves used in molding, extrusion, and packaging machinery. Failures often stem from proportional solenoid valve stiction, pilot transducer signal loss, or internal spool binding. Synchronics performs solenoid valve bench cleaning, transducer re-calibration, and full functional flow testing post-repair.
Integrated Proportional Valve Control Modules
Flex-O-Lators intelligent valve drivers with onboard PID logic, proportional solenoid duty cycle control, and pressure feedback compensation. Typical defects include firmware data corruption, transducer interface failures, and PWM amplifier stage burnout. Synchronics performs full diagnostic firmware verification and component-level repair of control electronics.
Pressure Transducer Interface Modules
Analog-to-digital signal conditioning electronics for Flex-O-Lators multi-transducer installations. Subject to thermal drift, capacitive coupling noise, and 4-20mA loop faults in humid Indian factory environments. Synchronics recalibrates ADC channels, isolates noise coupling paths, and re-establishes transducer loop integrity.
Proportional Solenoid Valve Coil Assemblies
Replacement and refurbished solenoid coils (24VDC, 110VAC, custom impedance) for Flex-O-Lators proportional directional spools. Coil insulation breakdown, open windings, and contamination-induced shorts are frequent. Synchronics stocks compatible OEM and tested aftermarket coils with rapid turnaround.

Common FLEX-O-LATORS INC Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in FLEX-O-LATORS INC equipment arriving at our workshop.
- ✓Solenoid coil open circuit and no valve response — Flex-O-Lators proportional solenoid coils experience insulation breakdown due to vibration fatigue, thermal cycling, and moisture ingress in humid Indian manufacturing plants. Continuous duty cycles on NG6 series valves accelerate winding degradation, leading to complete coil failure and loss of proportional valve actuation.
- ✓Proportional valve spool stiction and sluggish response — Flex-O-Lators pilot-operated proportional valves are prone to spool stiction when hydraulic fluid becomes contaminated with ferrous particles, water, or microbial deposits — common in Indian plants with marginal fluid maintenance schedules. Internal spool friction rises, causing slow response time and loss of control linearity.
- ✓Pressure transducer signal dropout and zero drift — Flex-O-Lators integrated proportional valve modules rely on 0-10VDC transducer feedback for closed-loop pressure control. Corrosion on transducer connectors, capacitive coupling from high-current PWM solenoid drivers, and 4-20mA loop breaks cause signal loss or offset drift, destabilizing LS logic.
- ✓Proportional solenoid valve nonlinear command response — Flex-O-Lators NG6 series proportional directional valves exhibit command hysteresis and saturation when onboard pilot stage amplifiers experience voltage sag, proportional spool spools become contaminated, or solenoid coil inductance drifts with temperature. This causes flow control instability in molding and extrusion applications.
- ✓Load-sensing pilot pressure loss and uncontrolled flow dump — Flex-O-Lators pilot-operated regulators depend on internal LS logic pilot valves and orifice restrictor plates to maintain system pressure. Wear on pilot spool lands, blockage of pilot porting from fluid contamination, or internal shuttle valve stiction causes pilot pressure collapse, resulting in uncontrolled flow to tank.
- ✓Firmware corruption in proportional valve control modules — Flex-O-Lators intelligent FPCM control modules store PID tuning and proportional solenoid trim data in non-volatile memory. Power surges, lightning strikes, and repeated brown-out conditions in Indian industrial grids cause flash memory bit-flip errors, corrupting calibration tables and disabling closed-loop proportional control.

Do you repair Flex-O-Lators proportional valve electronics in India?+
Yes. Synchronics Electronics repairs the complete Flex-O-Lators proportional valve product range — NG6 series directional spools, pilot-operated flow regulators, intelligent proportional control modules, solenoid drivers, and transducer interface cards. We offer pan-India door pickup and delivery from Vadodara, Gujarat, with service centers accessible from Mumbai, Delhi, Pune, Chennai, Hyderabad, Bangalore, and Ahmedabad. Same-facility repair minimizes downtime.
What is included in Flex-O-Lators proportional valve repair?+
Synchronics performs complete diagnostics: solenoid coil continuity and insulation testing, proportional spool freedom and response curve mapping, pilot stage amplifier gain and frequency response verification, pressure transducer signal path isolation, and load-sensing LS logic functional validation. We clean, recalibrate, refurbish, and bench-test to OEM performance standards. All work includes 12-month warranty.
How do I diagnose a failing Flex-O-Lators NG6 proportional valve?+
Common symptoms include slow spool response, sluggish proportional flow changes, pressure oscillation, or complete solenoid non-response to command signals. First, check 24VDC solenoid coil voltage and measure coil resistance with an ohm-meter (typically 8-12 ohms for 24V coils — open circuit indicates failure). Check pilot pressure at LS port (should equal load pressure +10-15 bar). If pilot pressure is absent, the LS shuttle valve or internal restrictor may be blocked. Contact Synchronics for bench diagnostics; we can isolate the root cause within 2-4 hours and provide repair or component replacement.
Do you stock Flex-O-Lators solenoid coils and replacement cartridges?+
Yes. Synchronics maintains inventory of Flex-O-Lators proportional solenoid coils in 24VDC, 110VAC, and custom impedance versions, plus LS pilot cartridges, shuttle valve assemblies, and proportional spool core kits. We also supply tested OEM and certified aftermarket components for rapid on-site replacement. Lead time for common NG6 and FOCR series items is 2-3 days. Emergency weekend shipment available.
What is the typical repair turnaround time for Flex-O-Lators equipment?+
Standard proportional valve and solenoid coil repairs are completed within 5-7 working days. Complex proportional control module firmware repairs and multi-cartridge load-sensing assemblies may take 10-14 days. Synchronics offers expedited same-day diagnostics and overnight courier return service on request. We communicate repair scope and timeline within 4 hours of unit arrival at our Vadodara facility.
How do I send my FLEX-O-LATORS INC unit for repair?+
Pack the unit securely and courier it to our Vadodara workshop. Include a note with the fault description and your contact details. We will log it into our system and WhatsApp you a job number within 24 hours of receipt. Doorstep pickup is available in Vadodara, Ahmedabad, Surat, Mumbai, and Pune.
What is the cost of repairing a FLEX-O-LATORS INC drive or PLC?+
Repair cost depends on the model and the fault. We offer a free diagnosis — once we identify the fault, we provide a fixed quotation before proceeding. Typical repairs cost 20–40% of the new unit price. We will never repair without your approval.
What warranty do you provide on FLEX-O-LATORS INC repairs?+
All repaired units carry a 6-month comprehensive warranty covering the same fault and related issues. If the fault recurs within the warranty period, we repair it free of cost.
Do you provide a no-fix, no-fee guarantee?+
Yes. If we cannot repair your FLEX-O-LATORS INC unit after diagnosis, you pay only the diagnosis fee (₹500–₹1,500 depending on the product). The unit is returned to you at no additional charge.
